Army Funds 两性色午夜 Aeronautics Professor to Research Drone Technology

A grant from the Army Research Laboratory has a 两性色午夜 University researcher flying high.

The grant provides more than $130,000 for Blake Stringer, Ph.D., assistant professor of aerospace engineering in 两性色午夜鈥檚 College of Aeronautics and Engineering, to study propulsion systems for a new generation of intermediate-sized unmanned aircraft systems (UAS), commonly known as drones.

鈥淚 would say that unmanned aircraft systems are becoming the disruptive tech of the 21st century in the aerospace and aviation industries,鈥 Dr. Stringer said. 鈥淭his technology is really changing the way we function as a society. So how do we control them? How do we implement them? How do we use them? How big can they be?鈥

That last question is exactly the one the Army wants Dr. Stringer to answer. 

Small consumer-grade quadcopters have been a favorite holiday present in recent years, while companies, like Amazon.com Inc., want to use them for package delivery. The military鈥檚 options for moving people and supplies through the air, however, remain limited to airplanes and helicopters. In a collaborative effort with Army Research Laboratory consultants and researchers at the University of Tennessee, Dr. Stringer will assess the feasibility of creating a drone that is sized somewhere in between.

鈥淲e鈥檙e taking something between zero and 55 pounds, and trying to make it 1,000 pounds,鈥 Dr. Stringer said. 鈥淲e want to make it so it鈥檚 able to drop supplies off or perform some mission.鈥

Dr. Stringer, who retired after 20 years in the Army, said the drone needs to serve a wide variety of functions.

鈥淢aybe you have soldiers in an urban area clearing a building and they need to be extracted from a top floor on a high-rise building, or you鈥檙e looking for something that can send supplies to a more remote area,鈥 he said.

Dr. Stringer鈥檚 project involves building an experimental test stand. 

鈥淲e鈥檒l put different sized electric motors and different sized rotors on it, and measure things like thrust, speed, thermal efficiency, acceleration, deceleration and vibration data,鈥 he said. 鈥淔rom that, we鈥檒l be able to determine how big is too big before we have to change the way we鈥檙e constructing things. When you go to scale these things from this small arrangement to something big, the dynamics of the rotor change.鈥

He said one of the main challenges for designing such aircraft is meeting the power requirements. 

鈥淗ow do we efficiently produce power that鈥檚 not around a gas turbine or a piston engine?鈥 he said. 鈥淚s it going to be some kind of hybrid propulsion system? Will you have a fuel cell that feeds into a battery and uses the battery for surge moments? There are a lot of different questions.鈥

Dr. Stringer said the grant is for a one-year project, but he hopes the research will be successful enough to take the group project to a second phase of support by the Army.
